The right end of the cold water valve 2 is the cold water outlet 7, the lower end is the cold water inlet 8, and the left end is the cold water valve pressure transmission port 9. There is an automatic switch valve core 10, the hot water valve 1 is provided with a quick-opening knob 22A on the upper end, the quick-opening knob 22A and the quick-opening valve core 21 are fixed by screws 20, and the cold water valve 2 is provided on the upper end with a decorative knob 22B, the decorative knob 22B and the cold water valve The joints of the main casings are fixed by threads.

It is worth mentioning that if the hot water use device such as faucet, water mixing valve or shower faucet at the 4th end of the hot water outlet is damaged, the valve can be manually forced to completely close the water supply by rotating the quick-opening knob 22A, which is convenient for users to use. Safe again.

As shown in FIG. 2 , the automatic switch valve core 10 includes a lower port 11 , a check rod 12 , a spring 13 , an assembly housing 14 , a piston disc 15 and a wedge 16 , and the lower port 11 is provided on the check rod 12 near the cold water outlet. 7 side, the lower port 11 is provided with a cold water channel port 19 that communicates with the cold water outlet 7, the check rod 12, the spring 13, the piston disc 15 and the wedge 16 are all arranged in the assembly housing 14, so The spring 13 is sleeved on the check rod 12, the piston disc 15 is arranged on the side of the check rod 12 close to the pressure transmission port 9 of the cold water valve, and the check rod 12 penetrates through the piston disc 15, and the piston disc 15 is fixed on the check rod 12 with the aid of the snap design and the wedge 16. The automatic switch valve core 10 installed according to this structure is quick and convenient to assemble and fixed firmly.

As an improved specific embodiment, the assembly housing 14 is provided with a filter screen 17 and a circlip 18 on the side close to the pressure transmission port 9 of the cold water valve, and a circlip 18 is provided on the side of the check valve 6 close to the hot water inlet 3 .

As an improved specific embodiment, O-rings are provided between the contact surface of the lower port 11 and the cavity wall, between the check rod 12 and the lower port 11, and between the assembly shell 14 and the contact surface of the cavity wall. The ring strengthens the seal to prevent water leakage.

The hot water inlet 3 of the hot water valve 1 and the cold water outlet 7 of the cold water valve 2 are respectively connected to the hot water outlet and the cold water inlet of the water tank of the water heater through pipelines.

It is worth mentioning that the water heater is any one of gas water heaters, electric water heaters, air energy water heaters, and flat-panel solar water heaters and other water tanks that are closed pressure hot water heating devices.

Further, the hot water valve pressure transmission port 5 of the hot water valve 1 communicates with the cold water valve pressure transmission port 9 of the cold water valve 2 through a connecting pipeline.

The function of the check valve 6: when the hot water terminal is closed, it can prevent the reverse leakage of the internal water pressure. Due to the function of the one-way valve 6, when the hot water terminal is closed, it is ensured that the water pressure of the hot water outlet 4, the water pressure of the P3 end, the water pressure of the P2 end and the water pressure of the P1 end will not leak in the case of water leakage in the water heater tank. The pressure is reversely released through the hot water inlet (P1, P2, P3 are marked in Figure 3) to ensure that the tap water pressure at the inner and outer ends of the check rod 12 is balanced. Move, close the cold water channel port 19, and stop supplying cold water to the water heater.

As shown in Figure 3, when the product device of the present invention is in use, the hot water outlet 4 of the hot water valve is installed at the inlet of the hot water pipeline reserved in the user's home wall, and the hot water pipeline and the user's hot water use terminal ( Such as: faucets, mixing valves, shower faucets, etc.) are connected. The cold water inlet 8 of the cold water valve is installed at the outlet of the cold water pipeline reserved in the user's home wall, and communicates with the cold water water supply pipeline. The hot water inlet 3 of the hot water valve is connected to the hot water outlet of the water heater through a water pipe, and the cold water outlet 7 of the cold water valve is connected to the cold water inlet of the water heater through a water pipe. The pressure transmission port 5 of the hot water valve is connected with the pressure transmission port 9 of the cold water valve through a water pipe.

When the user opens the hot water use terminal, the hot water flows out from the hot water outlet 4 of the hot water valve, and the water pressure of the hot water outlet 4 is relieved. In the same way, the water pressure at the P1 end is greater than the sum of the water pressure at the P2 end and the reverse pressure of the spring 13, the check rod 12 moves outward in the direction of P2, and the cold water channel port 19 is opened, and the cold water passes through the cold water inlet 8, the check rod 12, and the cold water. The channel port 19 and the cold water outlet 7 supply cold water to the water heater, the water heater works to heat, and the cold water is heated to become hot water. The hot water passes through the hot water inlet 3, the one-way valve 6, the quick-opening valve core 21, and the hot water outlet 4, and finally reaches the user's hot water use terminal.

When the user closes the hot water use terminal, the water in the hot water outlet 4 stops flowing, and finally the water pressure of the hot water outlet 4, the water pressure at the P3 end, the water pressure at the P2 end, and the water pressure at the P1 end are equal to the tap water pressure. The water pressure at the inner and outer ends of the check rod 12 reaches a balance, and under the reverse pressure of the spring 13, the check rod 12 moves to the right, closes the cold water channel 19, and stops supplying cold water to the water heater.

The non-return rod 12 of the present invention has a special design for reverse cold water seepage, and the design amount of reverse cold water seepage should ensure that it does not affect the normal outlet temperature of the user's hot water. Through reverse cold water seepage, even if the water heater has leaked, as long as the user closes the hot water use terminal, the water pressure at the hot water outlet 4, P3 end, P2 end, and P1 end can be reversed. The design of cold water seepage is finally equal to ensure that the water pressure at the inner and outer ends of the check rod 12 is balanced. Under the reverse pressure of the spring 13, the check rod 12 moves inward, closes the cold water inlet channel 19, and stops the supply to the water heater. cold water.

Special note: The hot water valve hot water outlet 4 of the present invention is provided with a quick-opening valve core. In addition to realizing the automatic control of switching the water according to the terminal use of the hot water, the user can also manually turn the quick-opening valve core knob to close it manually as required. Valve water supply brings great convenience and safety and well-being to users.
